Basic Online Advertising Campaign Guidelines

I used "Free SOAP":

• Free - People love free stuff and will usually happily hand over some details to get it.
• Social Advertising - Twitter, Facebook, MSN, LinkedIn, Forum Signatures etc...
• Oral Advertising - Real Life, Phone Calls, Talking, Creating verbal hype.
• Articles - Blog or Newsletter, demonstrating your expertise.
• Paid Advertising - AdWords, 1800banners, various advertising network.

You should give away something free or at the most shareware. It wouldn't hurt you to have a competition and give something away and collect potential customer email addresses for an opt-in mailing list. Social advertising is free as is Oral Advertising and Articles should link in with your free stuff and services if possible.

This structure should send you on your way for a successful internet advertising campaign.
